Got my 2005 1.9D van back in December, had a flat battery and had to be jump started to be driven away. I since replaced the battery as it was on its way out.

I then noticed the EML light (hadn't seen it on test drive) - Went and bought a Lexia 2000 to read the fault codes, there were a few old ones but i cleared them all just to be sure. The light stayed on

Drove to work as usual (45miles) mostly motorway and a few days later it went off. Came back on after 2-3 days and never went off, so i just continued to use the van. However in May the MOT test changed and they wont pass a vehicle with an Engine Management Light on, so mine has expired in June and I can't get a new one.

The Lexia shows no fault codes but does show " 0 Fault - Warning lamp lit" - so I'm kinda stuck. The only errors showing are those that appear due to no communication with the non standard radio and steering wheel controls.

The van drives prefectly normally, I have a spare van for parts due to being "Ripped off" , so I just need to know what it is so as I can start changing the relevant bits over.

The only thing that comes from a quick look around is the possibility of some damp somewhere in the ECU or perhaps BSI.

A few things to check/try but just guessing here:
Disconnect the battery for at least a half hour
Reset the BSI
Check the BSI for damp, also the ECU connections
Buy a cheap code reader, download the Torque app to a phone and check/clear codes.

I'll have a good look when I get a moment, its been like it all through the summer so I would have thought it would have dried out but nothing ventured.

The cheap OBD reader / Torque idea was just a guess in case Lexia will only clear faults that it can find, where a more generic app might simply send an overall clear. I have Lexia plus a cheap reader and they seem to work differently. It may not work, but it's less than a fiver to find out and you get a portable OBD reader into the bargain.

Spent over 20 minutes, doing BSI resets, apart from reseting the clock nothing appears to have changed, Took the van around the block for 5 minutes in the hope it may switch off when driven but still the same. Just ordered a cheap OBD reader as per your suggestion, should be a few days before it turns up. We will see how that goes.

BSI is bone dry, so i dont think its that....I did think it could be emissions related, but I don't think my 05 plate van has a dpf.
